Minor inconsistency in TFileTransport.cpp

[Jens Geyer <je...@hotmail.com>]

Right now I stumbled across some small inconsistency in TFileTransport.cpp.
The declaration is as follows (note the comment):

    writerThreadIOErrorSleepTime_ : uint32_t; // sleep duration in seconds 
when an IO error is encountered in the writer thread

it's initialized here:

  writerThreadIOErrorSleepTime_ := DEFAULT_WRITER_THREAD_SLEEP_TIME_US;

but at the usage, we can read this:

          T_ERROR('TFileTransport: writer thread going to sleep for %d 
microseconds due to IO errors', [writerThreadIOErrorSleepTime_]);

Since DEFAULT_WRITER_THREAD_SLEEP_TIME_US is defined as uint32_t( 60 * 1000 
* 1000) and usleep() also takes microseconds AFAIK, I would guess that the 
declaration comment should just read "microseconds" instead of "seconds"?
